JSXGraph

This release enables the dragging of lines, circles, texts and images. Axes are considerably improved as well as the handling of touch events on iOS and Android. Many bugs have been fixed, and the import of GEONExT and Intergeo files is more stable now. The documentation has been expanded significantly.

This version is a major rewrite of the code base, which results in significantly less code. The handling of visual attributes is now much more flexible. Feature requests have been added. The loading time has been improved as well as output to HTML5 canvas. Texts and images are integrated much more tightly. Finally, the API documentation has been improved by magnitudes.

This release adds support for the canvas element in Web browsers. This enables the use of JSXGraph on Android devices. Handling of multitouch events, locus computations, and root finding have been improved. New element types are B-splines, incircles, Reuleaux polygons, and roulettes (rolling curves). Mathematical texts may use MathJax now; the parsing of math syntax has been improved. Further, this release contains many bugfixes, the source has been refactored considerably, and unit tests have been introduced.

Beside many bugfixes, this release introduces conic sections (ellipse, hyperbola, and parabola) as new elements, as well as new chart elements like radar charts. There is also a new shortened syntax for geometric constructions. Reading of zip files has been enabled for all browsers, even IE. The quality of the Geogebra import has been improved, and the import of Cinderella files has been started. As a further feature, this release contains a color blindness simulation.

Support was added for multitouch devices like the Apple iPhone and iPod touch, and for Android based devices. JSXGraph runs quite smoothly on these devices.
